"I called five different companies from the Angi list before finding Colonna Consulting. When I called and I explained my situation to Nick (the owner), I immediately knew he was the one. Despite his tight schedule, he managed to fit me in on the same day. We hired Colonna and Nick to inspect our residential structural foundation. Nick responded promptly to my requests and explained everything clearly during the inspection. He completed the report within the same day. Working with him was a pleasure, and his professionalism made the process smooth and stress-free. Thank you very much Nick, for your fast response."

"Cigano identified a number of important changes to my architectural drawings to strengthen my structure (a car port). The changes recommended and implemented to my plans ensured my Town would issue a building permit. The Town had rejected my initial drawings and required its review and approval by a structural engineer or architect. Cigano really came through and its owner was easy to work with and highly professional. I would highly recommend Cigano."

"Julian delivered exceptional engineering analysis and design work for my residential gut rehab. He was consistently available, willing to help, and brought strong technical expertise to every discussion. His vision for an open‑wall layout led to the installation of a structural beam that completely transformed the home’s flow and created a true open‑concept space we never thought possible. He worked efficiently, communicated clearly, and carried himself with total professionalism. I highly recommend him to anyone looking to upgrade or reimagine their living space."

"After years of working with various contractors on major home improvements, we finally found our dream team with Duane Mainardi Builders! From the moment we reached out, Duane and his crew impressed us with their honesty and clear communication. Duane was always available throughout the project, and Keith, the site foreman, was simply incredible. He was onsite every step of the way and made the entire experience smooth and enjoyable. When we asked for changes after work had started, they welcomed every request with a genuine commitment to getting it just right. The siding crew was professional, skilled, and worked tirelessly. What we anticipated to be a four day job was impressively completed in just two and a half days. The final result? Gorgeous vinyl siding that has completely transformed our home?s look. We wholeheartedly recommend Duane Mainardi Builders if you want high quality siding done right by a team that truly stands behind their work. Michael and Vicki Sneed"

"Wes and his brother Mick are absolutely the best contractors! They have been in the business for many years and are extraordinarily skiiled in home renovations. They are an absolute pleasure to deal with. They are honest, trustwothy, very pleasant gentlmen who take great pride in their work. They are no nonsense, starting at 8AM everyday and working a solid 10 plus hour days. They delivered everything they promised and more. My wife and I could not have been more pleased with the quality of the construction, having converted a screened in porch to a three season room in no time. We have done many construction projects over the years from additions, to redoing kitchens and bathrooms to building a custom home. Based on on all of our experience, in our opinion, you would be hard pressed to find a better contractor to deal with than Alfred and Sons Construction. You get your moneys worth and a whole lot more! We highly recommend them!"
